Data Constraints and Idiosyncrasies
From Pat Hascall in Systems Engineering
• Data Constraints and Idiosyncrasies (LAT-TD-03775) is
intended to collect LAT quirks
– Started by Steve Ritz
– Goal is to identify, document and capture LAT features (that’s
not a bug, it’s a feature), gotchas, limitations or other issues
– The lists provided during the Cal and Tracker presentations
from this morning will be added to the document
• We need your help in documenting issues that you uncover
during your test data analysis
• If you find any issues that should be documented in this list,
please forward them to any of the following:
– Eduardo (he’s first on the list because he’s making me build
this chart for his presentation)
– Pat Hascall
– Steve Ritz

Sample Entry (Actually the only entry)
From Pat Hascall in Systems Engineering
• Item 1: ACD GARC Header Parity Bit Design Error
– One of the parity bits covering a portion of the serial data
stream between the ACD FREE cards and the AEM is
unusable, due to a design error. The issue and implications
are described in LAT-TD-03774. Alternative data integrity
checks, described in LAT-TD-03774, provide equivalent
coverage. These integrity checks must be performed and
monitored as part of the routine data reduction pipeline
processing.

Tkr1Y0
Tkr1DieEdge - Distance from die (wafer) edge of initial point
(0 is halfway between the dies, increases toward center of die)
Oh no!
Another project !

It was not easy…
• 29 people signed up for the Workshop
• 29 showed up in the dinner
– if someone did not pay please let me know, otherwise my
wife will kill me…
• ~50 to 60 attended the sessions !
– I think it worked well, but time will tell…
• To get all of us here was a lot of work since we had to
– Convince people that this was worthwhile
– Work hard to get the infrastructure needed
– Annoy people with continuous requests…

The SVAC Musketeers
C’mon Richard, this is not an unreasonable request…
No mercy,
Let’s get that
pipeline!
Warren
They won’t
escape from the
geometry review!
The calibration
packages are mine !

Eduardo
Special thanks to the three Musketeers who worked around the clock !

Meanwhile in the SAS kingdom…
Cardinal
“Richardlieu”
Here they come again…
The I&T Musketeers want
the towers assembled
upside down with a
diagonal readout and in a
grid with a dodecahedron
configuration
Of course, due
yesterday…
Our reasonable requests were
translated into the Gaudi
Framework…

•
Project lists
– Discussed this afternoon we have a lot of work ahead of us
User Manual
– I would like to prepare a user manual with the info from the workshop to
help you analyze data
Instrument Analysis VRVS meetings
– Weekly basis so that we can follow up
– I will call you periodically (to see if you miss California…)
– Biweekly reports by me in Steve’s ANA meeting
– Instrument Analysis List (IA) is set up (see next slide)
Working Meeting in July
– Core group (mostly local)
– Evaluate where we are
– Evaluate what to ask people to do with the EM2 data
•
•
Workshop 2 in September with the Collaboration Meeting
– 2 day workshop (TBR)
DATA TAKING starts in September/October !
– Would like to see you @ SLAC for a longer period to analyze data
